IMPROVEMENT IN AUTOMATIC GRAIN-BINDERS.

Spe0b:fcation forming parte?" Letters Patent No. 38,093, dated April 7,1863.

vTo all whom it may concer-n Be it known that I, ROBERT D. BROWN', ofCovington, in the county of Fountain 'and State of Indiana, haveinvented a certain new and useful Machine for Binding Grain 5 and I dohereby declare the following to be `a full and exact description of thesame,lreference being had to the accompanying drawings, makingpart ofthis specification, in which- Figure l is a side elevation of theapparatus. Fig. 2 is an end viewwith apart of the frame removed. Fig. 3is atop view. Fig. 4 is a horizontal section taken immediately beneaththe platform. Fig. 5 is a side view, illustrati ing a different mode ofdelivering the bound grain. Fig. 6 is a plan, partly in section,'rep'resenting the form of the machine shown in Fig. ,5. Fig. 7 is afragmentary plan, illustrating'a modiied'forin of the device by whichthe sheaves are deposited. Figs. 8, 9, and 10 are detached views, (on alarger scale,) which will be hereinafter referred to. Fig. 11 is aperspective view of the machine, illustrating its connection with oneform of automatic rake, and representing the form of depostingplatformshown in Fig. 5.

Similar letters of reference indicate corresponding parts in the severalviews.

The subject of rny-present invention is a machine for automaticallybinding grain with its own or other straw; and the inventionparticularly consists, first, in a device for applying the band, aroundthe gavel; second, in a device for insuring the correct position of thetwisting mechanism to receive the ends of the band; third, in a devicefor holding and twisting the ends of the band; fourth, in a peculiarmode of imparting motion to the twisting mechanism, so as to secure itshold upon the band; fifth, in devices for tucking the knot; sixth, in adevice for casting the finished sheaves successively into a commonreceptacle; seventh, in a peculiar device for depositing the finishedsheaves in heaps upon the roundeirhth in mechanism for counting4 g 7 a Arepresents the main frame,which may be of any suitable form, and isintended to be attached to, or form part of, a reapingmachine of anyconstruction, self-raking or otherwise. B is a cradle, in which thegrain is deposited by the raker, or by the automatic rake. `The saidcradle is provided at one end of its shaft with a segment-pinion, b,Fig. 4, by which it receives an intermittent motion at proper periodsfrom a segment-pinion, s2, on the main driving-shaft S, after which itis held for a limited period by a cam-surface, s. On the said pinion Blare stationary guardteetlnfbeneath which the gavel is thrownv by thecradle B; b is a spiral spring, by which the said cradle is restoredtoits normal position when the pinion is released. CV Gl, C C? representa pair of duplex compressing-arms,in which the gavel is deposited by thecradle B, and which are thrown up at proper intervals by means ofpinions c1 Vupon their `shafts c, driven by la cogged segment, c5, onthe shaft. cl is a camwheel upon the shaft C2, the rotation of which, asthe arms C C are raised, turns their pivoted members C1 upon the pivotsc, in such manner as to close the jaws c4 and grasp the ends of a bandprevionsl y placed therein. The said jaws are stayed by a pin and slot,c6, permitting 'them the needful play, but preventing their separationin any other way than. edgewise. D D are jaws, pivoted at d d to thelower end of a hollow shaft, D', which isjournaled in the main frame. Eis a shat't iitted to turn within the hollow shaft D', and provided atits upper end with a bevel-pinion, E', by which it is rotated. At itslower end the shaft E is formed with lateral projections je, adapted tobear against arms zl, projecting inward from the jaws D, so that aslight rotation ot'- the shaft E within the hollow shaft D will expandthe arms d1, and thereby contract the jaws I) and cause them to gripeany object which may have been placed between them. Springs d2, bearinginward against the arms d1, restore the jaws to their open ornormalposition when released. Fig. 8 represents an axial section of theshaftsD E with the jaws attached; and Fig. 9, a horizontal section ofthesame, taken immediately above the jaws. F F' are a pair of parallelshafts, connected by yokes f2, and geared together by cog-wheels f 3, sothat rotation imparted to one of the said. shafts will besinniltancously communicated to the other in theopposite direction. VTheshaft F carries a tucking'handJ', formed with serrations or fingers, andthe shaft F carries a pair ot' claws, j", constituting a bearing betweenwl'iich the tucking-hand works. The shaft F isjournaled in the upper endot' ,an arm, G, which is fulcrnnied atg to the main frame. The shafts FF are fitted loosely within segmentalguides H H, coucent'ific with thefulcrumg ofthe arm G. To the sides ot' the said guides are securedtoothed racks h h., which gear with .pinions' f4 on the shaft F, so thata rotary motion will be imparted to both theshafts as they traverse theguides H. I is a wheel running` upon a stud-shaft secured to the mainframe. The said wheel is driven through the medium of bevel-gearing jfrom the shaft J, and carries two cogged scg1nents,zt', secured to itspe. riphery in dit't'erent planes. The cogged segmenti gears with acog-wheel, 7s, on one end ot' a horizontal shaft, K, on the other endot' which shaft is a bevel cog-wheel, kl, which, gearingiwith thebevel-pinion E', before referred to, imparts an intermittent rotation tothe shaft E, and' through it to the jaws 1') and hollow'shai't D. Aspring-stop, k2, Fig. 2, engaging in a hole in the wheel k, as it isrcleased by the cogs lL", prevents the. subsequent displacement-of thesaid wheel, and retains the jaws D in proper position tov receive theends of the band. i2 is a cam on the wheel I,

employed to retract the stop k2 when the wheel k is again to be set inmotion. The cogged segment il gears with a corresponding segment, g1, onthe yarm (l, in order to throw the said arm forward and advance androtate theY shat'ts F F', as before explained. ASprin gs g2 g1", ol' anysuitable form, restore the said arm and shafts to their retractedposition when released by -the segment il. Fig. 10 shows one ol" theguidesH and an end view oi the shafts in their retracted positions.Their advanced position is indicated in thesame figure.

L is au arm, formed with projecting fingers Z, and attached to a shaft,M, which receives a rotary motion at proper intervals through the mediumot' bevel-cogged segments m m on the shafts L2 and M, to throw up thearm L and deposit the bound sheat' upon a` table, N.

Lines at' L2, in Figs. and 4, represent an a1 An which may be used as asubstitute for the arm L, to throw the bound shea'f sidewise instead ot'backward.

The form of gaveling apparatus which has been described is adapted foruse with harvesterralies which deliver the cut grain in a compact massat the side or end ot' the platform. 4The grain, i n this case, isreceived at the point indicated by au arrow in Fig. 4. For machineswhich deliver the grain in a wide swath, by rakes having a circularsweep, or for other forms of machines where it. may be needful, thestationary guard-teeth Bare dispensed with and a second cradle isapplied, as shown at B2 in Figs. 2 and 4. In

this case the grain will. be received in the direction indicated by thearrows in Fie'. 4. This position of the raking-platform admits ot theuse of the arm L2 to cast the shea-tv sidewise instead ot' backward,which device is preferable where circumstances admitof its use.

The table N is pivoted at n to the main frame, and supported in theposition shown in the drawings by means of a hook, a', liig.. 1, nearits front edge engaging under a rc.-

volving disk, 0.' The disk O receives'a rotary motion by means ot' avworm. s2., on the main driving-shaft S, gearing witha pinion, o, on theshaft o ot' the disk 0, the parts being so constructed and combined thatone revolution will be imparted to the disk O during twelve or any otherdesired number of complete `ni0- tions of the bindingmechanism. XVhenthe disk has completed a revolution, a slot therein (shown at o2 in Fig.4) releases the hook nl, and permits the rear edge ot' the table to fallby the gravity of the snperincumbent mass ot' sheaves. Cordsp p,attached to the rear edge of the table N, and passing around arollcr,p',

in the upper part ot' the frame, draw up a cur tain, P, as the table Ntalls,and by these means the sheaves are deposited in dozens upon theground at the rear ot' the machine. A spring', (2, restores the table Nto its upper position as soon as it is relieved ot" the weight ot' thesheaves, and this, loosening the cords pf, permits the curtain l to fallby its'own gravity.

The above-described'apparatus willdeposi t the sheaves in the wake ofthe' machine. It

it be desired to deposit them at one side, the

mechanism may be employed which is represented in Figs. 5, (i, and l1.vIn .this illustrI tiouthe curtain 1J3 is transferred from the back tovthe side oi' the machine, and-the pivot n2 of the table N2 is placedlongitudinally-instead ot' from side to side. A hook, n, rests upon theslotted disk 0, the saine as before. is a bolt engaging in an aperturein the frame to support the rear side of the table. ,The said bolt isretracted by a spring, n3, when the disk O is in position to permit thedescent of the table, but at other times is pressed outward .by aneccentric or cam, o3, beneath 'the disk O'. A modified form 'of thisdevice shown in Fig. 7. The spring-rod N4 is counected by a lever, n, toa bolt, N5; so that the pressure of the spring n3 will advance the saidbolt, and that otl the cam or eccentric on will retract it. By usingthis device in connection with an oblique catch, as shown at a 1n Fig.

5, it may be adapted to retain the table in for receiving sheaves, hasan inclination toward its discharging side or end,-in order to cause agreater accumulation of sheaves Aat that part where their weight is t0tilt the table, and also to produce such a slope as (with a' slightadditional tilting) will insure the discharge of the sheavesV when thecurtain is raised. i

In order that it may have the needful strength and rigidity, thestandard Af, or that part of the main frame which supports the twistingand tuclcing mechanism, is cast in one piece, together with the bearingsand attachments, so far as practicable.

a represents a shield covering the faces of the tueker f and claw f1, inorder to protect them from becoming clogged with straw.

The operation is as follows: A baud of strawis first laid across the armL, with its ends in the jaws c4. The grain is then depositedautomatically or by hand-raking upon the cradle B, or between it and theguard B1, or secondary cradle B2. i The segment-pinions s b then elevatethe cradle B, and cause it to compress the gavel beneath the guard B,or, incase the double cradle is used, it is compressed between the twocradles. The arms U Cl then carry up the band and deliver its endswithin the jaws D. The shaft E then begins to turn, the etfectof whichis to first revolution, or as much more as may be needful. The bandbeing thus twisted, the tucki'nghand f is advanced and rotated,simultaneousl y tucking the twisted part of the band beneath that partwhich surrounds the sheaf, the latter being held by the claw fl toprevent its displacement. The advanced position 0f the tucker f and clawfl is shown in Fig. 10. Having done their work, the said tucker and clawand the cradle B and arms C C] are retracted by the action of theirrespective springs, as already described, and the bound sheaf is thrownby the arm L onto Vthe table N, which deposits on the ground, in themanner already explained, when the required number have been bound.

The front part ot' the apparatuson which the binding is performed mayrest upon or form part ot the platform of a reaping-m achin'e of anysuitable construction; but the table N, which carrie-s the mass ofsheaves, should'be supported on one or more independent wheels, toprevent undue or unequal pressure upon the reaping-machine platform.

Having thus described my invention, I wish it distinctly understoodthat' I do not limit myself to the precise arrangement,"form of parts,or details herein laid down, but propose to vary the same in any waywhich experience may prove to be desirable, so long as the essentialfeatures of the invention be not departed from.
